Most phonologists I know would probably use wedge for most of these since they’re stressed, because schwa is usually considered just an unstressed allophone of a bunch of different English vowels, and not an actual phoneme itself. Also, I have syllabic l in tunnel and barred i in cousin.
I came here to say this. A bunch of these vowels are definitely pronounced with a wedge. Even tried intentionally pronuncing the stressed vowels with a schwa, and it’s noticeably, jarringly off.
